title: Vestibular evoked myogenic potential according to middle ear condition in chronic otitis media with tympanic membrane perforation.
abstract: CONCLUSIONS
  Vestibular evoked myogenic potential (VEMP) function results can vary between individuals with different middle ear conditions. Therefore, by analyzing VEMP results after paper patching, we can predict the condition of the middle ear in chronic otitis media (COM) patients.
  
  
  OBJECTIVE
  VEMP responses decrease with impairment of sound transmission, such as in conductive hearing loss (CHL). COM with tympanic membrane (TM) perforation is a common disorder that causes various degrees of CHL. The aim of this study was to evaluate and clarify the VEMP responses in patients with COM with different middle ear pathology.
  
  
  METHODS
  This study included 50 patients with unilateral COM with TM perforation. Initial pure-tone audiometry (PTA) and VEMP responses were recorded. After paper patching, PTA and VEMP were re-performed. Each VEMP response was compared with those of the healthy controls. Moreover, VEMP responses between pre- and post-paper patching were compared.
  
  
  RESULTS
  There was a positive correlation between normalizing of VEMP parameters, such as p13 and VEMP asymmetry ratio (VAR), and reduction of air-bone gap in patients with COM after paper patching. The VEMP response in patients with COM with intact ossicle and clean mucosa was more normalized compared with those in patients with COM with different middle ear conditions.
